When smbd can't get the size it asks for it tries smaller sizes,
reducing by a factor or 0.8 each time until it finds a size the OS
accepts.
so it looks like your OS is refusing large IPC shared memory areas. If
this is Linux then look at /proc/sys/kernel/shmmax. For other OSes you
will need to read the man pages as I don't know where the limits are
stored.
